RAlLWAY-CAR.

SPECIFICATION forming part of Letters Patent N 0. 763,968, dated July 5, 1904. Application filed July 26, 1901. Renewed January 16, 1904. Serial No. 189,374. (No model) To all whom, it may concern.-

Be it known that I, JOHN DEW, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im provements in Railway-Cars; and I do hereby declar'e that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in railway-cars, and more particularly to a railway-car designed for high speed, of light and strong construction, adapted at high speed to be driven by a motor carried thereon. Heretoforev many serious obstacles have prevented the attainment of very high speed of a train. One of the most serious difficulties has been the enormous strain upon trackconstruction when trains of great weight are moving rapidlythereon. Another serious difficulty has been the vibration always incident to high speeds and which with the present railway construction are always a source of danger.

The object of my invention is to provide a car much lighter than any heretofore used and supported upon safety-trucks, which permit the car to be positively secured upon the track when in motion and in a manner to prevent derailment, and also to provide means whereby the car when running ata high rate of speed is supported almost wholly from off the truck.

The invention consists of the matters hereinafter described, and more fully pointed out and defined in the appended claims.

' 11 and 12 are details of the means for operating the lateral aeroplanes.

As shown in said drawings, A indicates a car-body pointed at each end the more readily to overcome atmospheric resistance and supported at each end on a safety-truck similar to that shown in" my prior application for safety-trucks, filed on the 23d day of March,

1901, Serial No. 52,483, and which comprises for each truck a pair of track-wheels B, journaled by means of antifriction-bearings upon a shaft or axle, and a plurality of safetywheels B, adapted to engage on the under side of a guard rail or rails supported intermediate of the track-rails, as more fully shown in Figs. 5, 6, and 7. Said truck is also provided with means for varying the pressure of the track-wheels on the track.

The car may be constructed of any desired material and in any desired manner, but preferably will be of very light weight as compared with the cars in ordinary use and the weight of its contents or load disposed along a median line, as shown in Fig. 6, (in which a passenger-car is shown,) thereby acting to balance the car equally upon the trackrails. Any desired method of propulsion may be employed, the motor or motors preferably being carried on one or both of the trucks in position to actuate the track-wheels.

For the purpose of entirely or partly supporting the car from off the trucks whenunder motion and also steadying the same from vibration due to its motion over slight inequalitiesin the track aeroplanes C O are provided on the top and sides of the car, respectively. As shown, the aeroplane O extends longitudinally of and is secured above the car, as shown in Figs. land 7, and approximates in width the width of the car-top and is concave on its under side transversely thereof. Said aeroplane C is so secured to the car as to permit of longitudinal and transverse adj ustment. A plurality of rods care secured at their upper ends along the edges or margins of the aeroplane and extend downwardly along and within the side walls of the car and through air-pressure cylinders c. A pistonhead 0 is rigidly secured on each rod within its cylinder. As shown, pipes c a are con nected in each end of the cylinder and may communicate with a source of air-pressure, either a pressure-tank, or an air-pump, or any preferred device, whereby air may be ad mitted into either end of the cylinder by the operator or motor-man, thereby actuating said rods and moving the aeroplane up or down to the desired adjusted position.

For the purpose of more securely holding the aeroplane in its adjusted position a drum 0" is journaled adjacent to said cylinder, a pinion is rigidly secured axially thereof, and a rack-bar c, rigidly secured on the lower end of each rod 0, extends upwardly into operative engagement with said pinion, thereby rotating the drum as the rod is moved up or down in adjusting the aeroplane. As shown, a wire cable passes around said drum and through sheaves located above the same and leads up wardly in close proximity to the corresponding rod cand at the rear thereof and is firmly united to the aeroplane, thereby acting to carry part of the upward strain thereon. A clutch is provided on each drum-shaft, and a slidable locking-bar 0 extends longitudinally of the car, and one of the members of each clutch is rigidly secured thereon in position to positively engage its complemental 'memberwhem moved in one direction and to release the same when moved oppositely. A lever or any desired means maybe provided to actuate said shift-bars.

In the construction illustrated in Fig. 7 the aeroplane C is rigidly secured on the car-top and the aeroplanes C C are adjustably pivoted on each side of the same and are transversely concave on the under. sides thereof. As shown, a casing D, secured longitudinally on each side of the car near the aeroplane C, forms a part of the car-roof and is concave on its outer side to correspond approximately with the curvature of the aeroplane G and is adapted to contain the same when retracted, as shown in dotted lines. Means are provided for adjusting said aeroplanes outwardly or in wardly comprising an operating-lever (Z, rigidly secured upon the shaft 0Z, upon which the aeroplane is pivoted, and which is adapted to be manually engaged by an operator to swing said aeroplanes to their adjusted positions.

Any desired means may be used to hold said aeroplanes in their adjusted positions. (Jonveniently a notched quadrant is rigidly secured on the car concentric with the shaft (Z, and a spring-controlled dog 0 carried on said lever, normally engages in said notches and acts to hold the shaft from rotation in whatsoever position the aeroplanes may be adjusted.

The operation of my device is as follows: Before the car is started the aeroplane C may be adjusted and, if preferred, may be used alone and acts to support a portion of the weight of a car on the atmosphere when the car is in motion. As the motion is acceler- BEST AVA lLABLE CW- ated the proportion of weight supported on the aeroplane constantly increases until, if preferred, the greater part of the weight of the car may be supported thereon. If desired, the adjustment may be made while the car is in motion, either to increase or decrease the amount of support afforded bythe aeroplanes. If it be desired to increase the lifting power of the aeroplanes, the same may be accomplished by adjustment or by exposing a larger aeroplane-surface upon one side of the car than upon the otheras when, for instance, a strong wind is blowing against one side of the car either or both of the aeroplanes C' may be thrown outwardly to a desired position and locked rigidly, as before described. Inasmuch as the car and its contents are supported to a very great extent upon the atmosphere, it is obvious that the vibration due to its motion over the track is minimized, thereby adding greatly to the comfort ofthe passengers and decreasing liability to accident. Obviously when a car so supported or partly supported on the atmosphere is driven at a high rate of speed it is importantto so secure the same upon the track as to preclude the possibility of derailment. For this purpose the guard-wheels B are secured upon the trucks and engage beneath the guard-rails, thereby preventing the lifting of the truck.

As a further improvement a gas-bag Gr may be employed at the top of the car. As shown, said gas-bag is secured to and beneath said aeroplane U and is of such form that when filled with a gas, such as hydrogen, it will aid materially in supporting the car. Furthermore, when such gas bag or receptacle is used the forward motion of the car and the airpressure created thereby on the lateral surfaces of the bag act to force a portion of the gas rearwardly of the car, thereby creating a less thickness of the bag at the front end than at the rear, thereby providing an upward curvature on the under and lateral surfaces thereof, which aids in supporting the car.

Obviously, if preferred, aeroplanes maybe secured rigidly on the sides or top of the car, or the bottom of the car may constitute an aeroplane and the car and its aeroplanes or the method of adjustment thereof may be varied, as preferred, and many detailsof construction may be varied without departing from the principles of my invention.
